First Claim
1. A control module for a solid state lighting device that includes a plurality of groups of solid state light emitters, wherein each group of solid state light emitters of the plurality of groups of solid state light emitters is independently controllable and is arranged to generate emissions comprising a dominant wavelength that differs from a dominant wavelength of emissions generated by each other group of solid state light emitters, and emissions generated by each group of solid state light emitters are arranged to be combined to produce aggregate emissions of the solid state lighting device, the control module comprising:
- a memory storing at least one operating instruction set; and
at least one processor configured to utilize the at least one operating instruction set to automatically adjust at different hours of a calendar day (a) luminous flux of the aggregate emissions and (b) at least one of correlated color temperature or color point of the aggregate emissions, responsive to at least one of (i) time or (ii) at least one signal indicative of an environmental condition;
wherein the at least one processor is further configured to utilize the at least one operating instruction set to automatically adjust at different hours of a calendar day at least one of (c) melatonin suppressing milliwatts per hundred lumens of the aggregate emissions or (d) relative gamut of the aggregate emissions, for a selected color point or correlated color temperature of the aggregated emissions.

Abstract
Lighting devices and methods utilize multiple independently controllable groups of solid state light emitters of different dominant wavelengths, with operation of the emitter groups being automatically adjusted by processor(s) to provide desired illumination. Operation of the emitter groups may be further affected by sensors and/or user input commands (e.g., sound patterns, gesture patterns, or signal transmission). Operation may be adjusted to compensate for presence, absence, intensity, and/or color point of ambient or incident light. Presence of five or more groups of solid state light emitters provide desirable luminous flux, color point, correlated color temperature (CCT), color rendering index (CRI), CRI R9, and luminous efficacy characteristics of aggregate emissions over a wide range of CCT values, and may permit adjustment of vividness (e.g., relative gamut) and/or melatonin suppression characteristics for a selected color point or CCT.
